Help Tip: If you have a question that has not been answered to your satisfaction in the archives, it is always best to start a new thread of your own. By starting your own thread, you will receive the maximum number of views by forum members.

Below are some additional forum policies in hopes of all iboats members will follow, Thank you.

1. Please do not reply to old topics or hijack existing topics. Old topics of a technical nature are like a library book, Please do not write in them.

2. Old topics should be considered archives and used for reference only. Please do not reply to them.

3. Do not take over someone else’s topic (aka hijack) with your own question, even if it is similar. If you have a question that has not been covered to your satisfaction in the archives, it is always best to start a new topic of your own.

4. If you have a question for the original poster (OP) and the topic is over 30 days old, send the OP a PM, he may not even visit the forums any longer, or may not notice your question in the old topic.

5. By starting your own topic, you will receive the maximum number of views by forum helpers that may not even notice your question when it’s posted at the end of someone else’s topic. And those answers will be specific to your particular issue.

6. Please do not post to topics that have been inactive for more than 3 months unless you are the original poster. We have very active forums and any topic that remains inactive for that long should be considered "dead". It is especially confusing when there is an entirely new question posted to an old topic.

7. Posting at the end of any topic is considered to be hijacking the original posters topic which in turn subjects the topic to be closed if it continues to happen thus not making it fair to the original poster in the future had for some reason he/she needed to return for additional information or provide an update of the problem solved which is always welcomed within a reasonable amount of time frame.

8. Please note that you should see a red banner pop up near the bottom of each inactive topic asking you not to reply to old topics. The Red banner will read: Please note this topic has been inactive for 90 days. For the best results, please start a new topic.

Thank you all in advance for doing your part in helping iboats run a smooth ship.

  • 3 hp Tanaka/Gamefisher idling and prop issues

    Hi all. After many, many years of trusty, reliable service my little 3 hp, air-cooled Gamefisher kicker motor is acting up. I believe the centrifugal clutch may be worn/broken as I can now spin the prop in either direction, even with the motor turned off, whereas I was unable to do so in the past. As a result, the prop spins even at the lowest idle settings. I used to be able to set the idle so low you could practically count the rpm without the prop engaging, then as you rolled on the power, the prop would engage and off you go. Now, the prop spins no matter what, and I can't get the motor to idle down like I used to despite multiple carb cleanings and fuel line inspections. It also bogs down and hesitates slightly when giving it more throttle, but I think that may be a separate issue. It's now as if the clutch is permanently engaged. It works great at higher rpms and can run WOT all day without issue, but it no longer idles like it used to. Is there any way to remove the power head to inspect/repair the clutch itself? I'd hate to have to get rid of it, but it may cost more to fix than its worth. Thanks for any help.

    I too have this motor but i just bought mine used. from my understanding the clutch is pretty easy to get to. beleive its the 4 screws on the bottom. as far as what to do once ur in ther is another story. my clutch seems to work properly but cant get it to stay running. I have pulled the carb off and cleaned it and everything looks in pretty good condition. do u know where to get replacement parts for it?

      I've my TOB300 for a long time as a trolling and "get-home" motor. Aside from being an ultra light, its also a very reliable motor. Dropped it once and cracked the plastic shroud ( which I removed, now I can see the level of gas in my tank), cracked the flange on the carb intake, cracked the gas tank( can only fill it halfway now), and damaged the vent on the gas cap. I have been searching for a while for parts source with no luck 'til I came across this website OEM Parts .You might want to give this a try.

        it is as easy as you say to get to the clutch. I did find the clutch material for the small flex metal clutch not connected, I epoxied it back to the spring steel. BUT this is a discontinued part, does any one know of a place to get replacements. Right now I will let it set for 24 hrs to test with epoxy, I have done that before with good results.
